This may have been asked already, but with ALL of Northern Europe Airspace closed down does that also include Fighter Jets AWACS etc???

I'm guessing 5th gen is similar to MKV

It's most likely just a plane with major upgrades.

Thanks so much for this post, I have been wondering how they figure out which generation a fighter plane is. Do they include bombers in the generation lists, as I have never come across a bomber being described as a "3rd generation bomber" for example.

In my opinion, the jet fighter classification would be:

1) subsonic straight wing
Examples: Meteor, F-80 Shooting Star, F-84G Thunderjet, F9F Panther, MiG-9 "Fargo", Ouragan,

2) subsonic swept wing
Examples : F-84F Thunderstreak, F-86 Sabre, F9F Cougar, MiG-15 "Fagot", MiG-17 "Fresco", Mystere IV, J29 Tunnan

3) transonic & low supersonic
Examples : F-100 Super Sabre, MiG-19 "Farmer", Super Mystere, J32 Lansen, Hunter, F-102 Delta Dart, F-11 Tiger, ...

4A) tactical supersonic planes around Mach 2 class
Examples : F-104 Starfighter, F-8 Crusader, F-5 Freedom Fighter / Tiger II, Mirage III, BAC Lightning, J35 Draken, MiG-21 "Fishbed", Mirage F1, JA37 Viggen

4B) long range supersonic planes around Mach 2 class & beyond
Examples: F-4 Phantom II, Mirage G8, F-106 Delta Dart, Su-9/11 "Fishpot", Su-15 "Flagon", MiG-23 "Flogger", MiG-25 "Foxbat", YF-12A Blackbird, J-8 "Finback", CF-105 Arrow

5A) tactical fighters around Mach 2 class with higher maneuverability
Examples: F-16 Fighting Falcon, F/A-18 Hornet, F-20 Tigershark, Mirage 2000, JAS39 Gripen, Typhoon, MiG-29 "Fulcrum", Rafale

5B) long range fighters arround Mach 2 class with higher maneuverability:
F-14 Tomcat, F-15 Eagle, Su-27/30/33/35 "Flanker"

6A) stealth tactical fighters:
F-35 Lightning II

6B) stealth long range fighters:
F-22 Raptor, YF-23, Suhoi T-50, Chengdu J-20
